As the system is now - anyone can alter the chosen photos, and their sequence. I think that is best.
Since I use the taxon photos for IDs (we don’t all have field guides or access to paywalled sites for all the things) - if the taxon specialist says - see the green hairs on … - then I make sure Green Hairs is in the first few - maybe using a picture directly from that newest ID.
But I would rather have 12 (random but taxon) pictures than ‘no adult female on iNat’. That in turn is an argument for annotating iNat obs.
Relevant taxon info is another reason to think twice, before changing the pictures.
PS we have 2 Forum threads running in parallel.
